V tion.

The present invention has reference to iin.- provelnents in shock absorbers for Vehicles, ond relates more particularly to the construction, arrangement sind cooperation ot parts., as will hereinafter be described und clsirned in the appended claims.

"llie well known shock absorbers, consisting,` of relntivelyyieldeble 'friction members, are now used generally one for each Wheel. According to the present invention this nurnloer is cut down to two, by positioning the shock absorbers in such manner that their exis extends in the vertical longitudinal center plone of the vehicle.

ln order to ineke this invention-incre rendily* understood, l Will'now describe it with reference to tlie accompanying drewing, in'

Which- Figure l shows e cross-section through the device, end Fig. 2 s liront View ot seine, in position on the Vehicle.

The slioelr reducer essentially consists ofl e cylindrical housing o with letersl eut-outs, journaling two snnulsrly trouglied vdisks c. with arms e'y laterally' extending; through these cutouts. l`lie dislis tace with their liollows end cooperate Witli the friction men'ibers d, e, contoured according vto the respective 'dislr surtaces. its shown,

the housing is 'provided with s central pessege ttor tlie Slis-it n, ot the crsnlt handle m, and the 'friction parte are ot correspondingly annuler shepge. The cover or een j? cl the housing een be displaced on the vinner cy'linn di'icnl Well g toward, or sway from, the outer *Friction 'member Z by ineens of s nut t' one another;

threading on the 'front endet the Well cylin- -der g, and s spring' 7a, is interposed between nut and cap. lille housing is suitably secured to s cross member 7: oli the vehicle freine Z, sind the outer ends of the absorber :u'ins a ure bent downward end are twisted as et o, und ere directly secured to the .crossexlc p of tbe Vehicle. Laminated springs g are interposed between the crossnnle and the vehicle freine proper.

What l claim is:

l. The combination with e Vehicle trono@v` s cross-axle, and springs interposed between seid trame and said axle, of e shock absorber, located midway of said crosssxle, comprising two centrally perforated, ennularly trouglied friction disks, laterally er;- tendingarms thereon with down-turned and twisted outer ends, annular friction wenn bers, an annuler housing; inclosing seid :triction parte, :ind ineens for controlling the 'friction pressure between these latter parte,

seid twisted absorber arms being secured to cross-axle end seid housing being secured to the vehicle treme.

2 A shock absorber for vehicles, comprising' e cylindrical 'housingP with lateral cut outs, annulurly troug'bed friction disks therein, e littoral. erm ou encli ot seid disks extending; outwardly through seid cut-outs and singularly bent and twisted neer the outer end., said friction disks facing eecll other with their bellows, friction members cop existing respectively with the outer end inner 'feces ot said disks, und srljustnble ineens for controlling the friction pressure between seid friction ports.
